19 Preface The StarKeeper II Network Management System (NMS) SNMP Proxy Agent is an optional add-on software package for the StarKeeper II NMS Core System. It enables customers who subscribe to SMDS or Frame Relay services to manage their own private virtual networks by allowing them to monitor the interfaces they use on the public data network. The StarKeeper II NMS SNMP Proxy Agent supports SMDS and Frame Relay services on BNS-2000 networks and certain Frame Relay services on BNS-2000 VCS networks. The SNMP Proxy Agent software is installed on the host processor for the StarKeeper II NMS Core System. (See the StarKeeper II NMS Planning Guide for the models that support the SNMP Proxy Agent.)The StarKeeper II NMS Core System must also be connected to a TCP/IP Local Area Network (LAN). Purpose of the Document 0 This guide covers the installation, administration, and maintenance of the StarKeeper II NMS SNMP Proxy Agent and is intended for the StarKeeper II NMS administrator. This guide includes procedural and reference information. Before you install the SNMP Proxy Agent software, read Chapter 1, Introduction and Chapter 2, Administration and Maintenance Procedures to get an overview of the product and your administrative tasks. Refer to Chapter 3, Database Management when you are ready to register an SNMP Manager in the SNMP database. Chapter 5, SNMP Manager Configuration describes the information that the administrator of an SNMP Manager needs in order to begin using the SNMP Proxy Agent. Chapter 4, Troubleshooting and the Appendices include information that is useful for troubleshooting and maintaining the system. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 xix

20 Terminology 0 The following terms are used frequently in this guide. For a complete list of terms and their definitions, refer to the Glossary. SNMP Manager a customer's SNMP management station.

23 Introduction 0 1 This chapter covers basic SNMP concepts and describes the features and architecture of the StarKeeper II NMS SNMP Proxy Agent software. SNMP Concepts 1 Simple Network Management Protocol (SNMP) is an open industry-standard network management protocol. SNMP enables an SNMP Manager and an agent to communicate. An SNMP Manager controls and monitors the customer's private data network. It can also request information from the agent. An agent is a device which carries out the requests of the SNMP Manager. In addition, the agent automatically notifies the SNMP Manager when changes occur to network devices that may impact the network, without the manager's explicit request. This type of information transfer is called a trap. An SNMP Proxy Agent is a technique that allows the proxy to take SNMP requests and translate them into transactions needed by managed machines that do not support SNMP. The management information accessed through SNMP is conceptually organized into a database called the Management Information Base or MIB. SNMP uses the User Datagram Protocol (UDP) at the transport layer and the Internet Protocol at the network layer for communication. Each SNMP Manager and SNMP agent are identified by a valid IP address. Figure 1-1 shows how information flows between the SNMP Manager and agent and which network layers exist on the SNMP Manager and agent. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 1-1

24 Introduction Manager Agent SNMP Requests SNMP (Get Request PDU, Get-Next Request PDU Set Request PDU) SNMP Replies (Get Response PDU) SNMP Get, Set Objects MIB SNMP Traps (Trap PDU) UDP UDP IP IP Figure 1-1. Communication between SNMP Manager and Agent Features of the StarKeeper II NMS SNMP Proxy Agent 1 The StarKeeper II NMS SNMP Proxy Agent enables customers who subscribe to SMDS or Frame Relay services to manage the public network interfaces they use. The StarKeeper II NMS SNMP Proxy Agent communicates with many SNMP Managers, as illustrated in Figure 1-2. The customers SNMP Managers manage their private data networks, as illustrated by the bubbles on the left side of Figure 1-2. With the SNMP Proxy Agent, customers can also monitor the network interfaces they use on the SMDS/Frame Relay public network, as shown by the right side of Figure StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

25 Introduction Customer 1 Network SNMP Manager SMDS/Frame Relay Public Network Customer 2 Network SNMP Manager Agent Customer N Network SNMP Manager Figure 1-2. SNMP Managers and Proxy Agent What the SNMP Proxy Agent Provides 1 The SNMP Proxy Agent allows an SNMP Manager to do the following: Retrieve performance measurements, error counts, and logs. Retrieve configuration information. Monitor the current status of an interface. Receive traps (alarms) on changes in the status of an interface. Receive authentication-failure traps. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 1-3

26 Introduction Functional Capabilities of the SNMP Proxy Agent 1 The StarKeeper II NMS SNMP Proxy Agent supports the following functional capabilities: Supports SMDS and certain Frame Relay services. SMDS interfaces are provided by the Access Interface (AI) modules on a BNS-2000 node. Frame Relay interfaces are provided by the M2-Frame Relay Module (M2-FRM) and the Frame Relay Module (FRM) on a BNS node and the FRM on a BNS-2000 VCS node. Supports the following SNMP primitives: Get Request PDU For each variable in the Get Request PDU, the SNMP Proxy Agent returns the value of the object. Get-Next Request PDU For each variable in the Get-Next Request PDU, the SNMP Proxy Agent returns the value of the next object in its MIB. Get Response PDU The SNMP Proxy Agent responds to the SNMP Manager's Get Request PDU or Get-Next Request with this PDU. Set Request PDU For each variable in the Set Request PDU, the SNMP Proxy Agent adds or deletes the value of the object. Trap PDU The SNMP Proxy Agent sends unsolicited traps to the SNMP Manager. Assures that only SNMP Managers that are registered in the SNMP database gain access to the SNMP Proxy Agent. Allows SNMP Managers to get information only for the interfaces that have been assigned to them. Restricts the number of requests that an SNMP Manager can make to a particular node. Refer to Flow Control and Usage in Chapter 3, Database Management for more details. Supports a subset of MIB II Objects The SNMP Proxy Agent supports the system group, a subset of the interfaces group, and the snmp group of objects. Supports Lucent Enterprise MIBs Lucent Enterprise MIBs identify additional network management information that an SNMP Manager can access. These MIBs are registered as enterprise vendor-specific MIBs and are described in Appendix C, Supported SNMP MIB Objects and Traps. NOTE: The Proxy Agent continues to support the superseded AT&T Enterprise MIBs, which were previously used by the product. Both 1-4 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

27 Introduction versions of the MIBs define the same objects; they simply name them differently. However, we recommend that the Lucent MIBs be used. Connectivity 1 Figure 1-3 is an example of connectivity between an SNMP Manager and the SNMP Proxy Agent. In this example, the SNMP Manager uses the public SMDS/Frame Relay network to gain access to the SNMP Proxy Agent that is connected to the same network. IP routing configuration must be made at the SNMP Manager and the SNMP Proxy Agent routers to ensure proper connectivity.

28 Introduction Database Provisioning 1 The SNMP Proxy Agent accesses data in two databases: the StarKeeper II NMS Core System database and the SNMP database. The SNMP database is administered using the sksnmpcf or the sksnmpxadm command. Before SNMP Managers can access data about the SMDS or Frame Relay interfaces they use, the StarKeeper II NMS administrator must enter the following information in the SNMP database: System Information identifies the system, where the SNMP Proxy Agent resides, and the organization or person to contact when there is a problem with the SNMP Proxy Agent. Network Interfaces identifies the interfaces that the SNMP Proxy Agent supports. Each interface is assigned a unique Id called an Interface Index. An interface is identified by node name, module address, and port as well as other attributes of the interface. Customer Views and Customer View Members a Customer View is a name for a set of Interface Indices that an SNMP Manager can manage. A member of a Customer View is an Interface Index. Subscriber Information identifies the SNMP Manager by a unique name (Subscriber Identifier), IP address, and a set of passwords (community strings) and Customer Views, as well as several other attributes. In addition there are two other types of information kept in the SNMP database: Flow Control Information provides the capability to limit the number of requests an SNMP Manager can make to a particular node in a 15-minute interval. Usage Information provides counts on the SNMP usage by a particular SNMP Manager. See Chapter 3, Database Management for more information. Software Processes 1 This section describes how SNMP requests are processed and the internal processes of the SNMP Proxy Agent. How an SNMP Request is Processed 1 The SNMP Proxy Agent processes an SNMP request (Get Request PDU or Get- Next Request PDU) by completing these steps: 1. The SNMP Proxy Agent verifies that the request is from an SNMP Manager registered in the SNMP database. 2. The SNMP Proxy Agent verifies that the community string (password) in this SNMP request is valid. 1-6 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

29 Introduction 3. The SNMP Proxy Agent verifies that the SNMP Manager has access capabilities for the requested information by checking the SNMP Manager's assigned Customer View in the SNMP database. 4. The SNMP Proxy Agent retrieves the appropriate network management information from the StarKeeper II NMS Core System database, SNMP database, or the node. 5. The SNMP Proxy Agent translates the information into SNMP format and sends it to the SNMP Manager. Figure 1-4 shows the SNMP Proxy Agent processes and the paths that information takes.

33 Administration and Maintenance Procedures 0 2 System Administration Tasks and Responsibilities 2 This chapter gives you an overall view of the system administration and maintenance tasks that are your responsibility as administrator of the SNMP Proxy Agent. Additional information on the commands mentioned in this section is provided in Appendix A, User Reference. Prerequisites 2 The StarKeeper II NMS SNMP Proxy Agent software can be installed on a Hewlett-Packard 715/75, 720, or 730. The StarKeeper II NMS Planning Guide lists all of the supported configurations. Before installing the StarKeeper II NMS SNMP Proxy Agent software, make sure the following have been completed: The StarKeeper II NMS Core System software must be installed on the HP system before you add the SNMP Proxy Agent software. The appropriate software licenses must be installed on the StarKeeper II NMS Core System. Licensing is required for all StarKeeper II NMS software. Software licensing is required for all of the StarKeeper II NMS application packages before they can be loaded. Before the SNMP Proxy Agent can support SMDS or Frame Relay interfaces, the appropriate licenses must be installed on the StarKeeper II NMS Core System. Separate StarKeeper II NMS SNMP Proxy Agent licenses are required for SMDS and for Frame Relay support. For detailed information on software licensing, see the StarKeeper II NMS Installation Guide. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 2-1

34 Administration and Maintenance Procedures Installation 2 For instructions on installing the StarKeeper II NMS SNMP Proxy Agent software, refer to Getting Started with StarKeeper II NMS for Software Package System and Upgrade. The SNMP Proxy Agent software is, by default, installed in the following base directory: /usr2/snmp. Logging In 2 To use any of the SNMP Proxy Agent commands, log in to your StarKeeper II NMS Core System as cnmsadm. When you log in as cnmsadm, you inherit the SNMP Proxy Agent environment variables defined in the file $SNMP_ROOT/etc/env/SNMP.vars. Starting the SNMP Proxy Agent 2 Before starting the SNMP Proxy Agent for the first time, connect the StarKeeper II NMS Core System processor to a TCP/IP Local Area Network (LAN). Refer to the appropriate LAN manual for instructions on adding your StarKeeper II NMS Core System processor to a LAN. Procedure 2-1. Starting the SNMP Proxy Agent Processes 1. Log in as cnmsadm. 2. Verify that the StarKeeper II NMS Core System software is running. The StarKeeper II NMS Core System must be running when you start the SNMP Proxy Agent. 3. If you are starting the software for the first time, configure the SNMP database before allowing SNMP Managers to access the SNMP Proxy Agent. For details, see Chapter 3, Database Management. 4. Enter the sksnmpstart command. 5. When the system prompts you for a password, enter the root password. 6. After you enter the correct root password, the SNMP Proxy Agent daemon processes start. See Appendix A, User Reference for more detail on sksnmpstart. 7. To verify the operational state of the SNMP Proxy Agent, use sksnmpstat. See Appendix A, User Reference for details on sksnmpstat. NOTE: If you reboot the StarKeeper II NMS Core System, the SNMP Proxy Agent will automatically start up. You do not have to start it manually. 2-2 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

35 Administration and Maintenance Procedures If you manually start up the StarKeeper II NMS Core System software, the StarKeeper II NMS Core System start-up script automatically invokes the sksnmpstart command to start up the SNMP Proxy Agent processes. You will need to enter the root password before the SNMP Proxy Agent processes can start up. Stopping the SNMP Proxy Agent 2 If you need to stop the Core System, you must stop the SNMP Proxy Agent first. If you do not stop the SNMP Proxy Agent first, the SNMP Proxy Agent terminates abnormally. Use the sksnmpstop command to stop the SNMP Proxy Agent. SNMP Database Configuration 2 Before you allow SNMP Managers to access the SNMP Proxy Agent, register the SNMP Managers and identify the network interfaces in the SNMP database. To configure the database, you use either the ASCII or Motif version of the SNMP Proxy Agent menus and screens. For more details, refer to Chapter 3, Database Management. Synchronizing the SNMP Database 2 In addition to the data you provide on network interfaces in the SNMP database, configuration and measurement information is needed from the nodes and from the StarKeeper II NMS Core System database. To collect this necessary data, you use two commands: sksnmpndsync and sksnmpdbsync. These commands are described in Chapter 3, Database Management. Testing 2 After you start the SNMP Proxy Agent and configure the SNMP database, test the SNMP Proxy Agent by using one of these commands: sksnmpget, sksnmpnext, sksnmpset, or sksnmpwalk. These commands are used to verify that the SNMP Proxy Agent can get and send MIB data. In terms of data retrieval, these tools act like SNMP Managers. Your local system must be registered as a subscriber in the SNMP database in order to use these tools. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 2-3

36 Administration and Maintenance Procedures Try the following simple tests: sksnmpget <address> <community> sysdescr.0 sksnmpnext <address> <community> system sksnmpset <address> <community> [<object_id> <type> <value>] sksnmpwalk <address> <community> system BNS-2000 Initializing, Backing Up, and Restoring the SNMP Database 2 The SNMP database snmpdb is created automatically when you install the SNMP Proxy Agent software. In rare instances, you may need to use the sksnmpidb command to recreate and reinitialize the database.! WARNING: The sksnmpidb command removes all of the existing data in the database and also removes the database itself. Procedure 2-2. Reinitializing the Database: 1. Back up the data in the SNMP database using the sksnmpbdb command. 2. Enter sksnmpidb. 3. Restore the database using the sksnmprdb command. Backups should be done after the SNMP database is initially configured, and afterwards on a regular basis and after you make extensive changes. The SNMP database can be backed up to a directory that you specify or to tape. Troubleshooting 2 If problems occur, look in the log file, $SNMP_LOG/snmp_agent.log. This log lists general events and errors that occur when the SNMP Proxy Agent is running, such as when the SNMP Proxy Agent was started or stopped, and if there have been any unauthorized or invalid attempts by SNMP Managers to access the SNMP Proxy Agent. The log file is a flat ASCII file. To browse through the log file, you can use such UNIX tools as pg, cat, or vi. Refer to Chapter 4, Troubleshooting and Appendix B, Log and Error Messages for more information. 2-4 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

37 Administration and Maintenance Procedures Procedure 2-3. Provisioning Network Interfaces for CNM Service Before you can bring your network interfaces (module ports) into CNM service, complete the following: 1. Make sure that StarKeeper II NMS is running on your Core System. 2. Configure the nodes on your Core System so that StarKeeper II NMS can monitor the nodes. 3. Configure the ports (SMDS or Frame Relay) on your BNS-2000 or BNS VCS nodes. 4. Run skload and cfg_sync to make sure that the StarKeeper II NMS Core System database is populated with the node's module port information. 5. Make sure that the Core System is collecting SMDS and Frame Relay measurements from the nodes. 6. If you have SMDS interfaces, use Network Builder to logically administer your SMDS network. 7. Enter the network interfaces, Customer Views, and subscribers into the SNMP database by using the sksnmpcf or the sksnmpxadm command. 8. Make sure that the SNMP Proxy Agent is running on your Core System. Guidelines for Processing Set Requests 2 CNM customers, using their SNMP Managers or SNMP management applications, can submit Set Requests. For example, an SNMP Manager can add or delete SMDS individual or group screening addresses. These requests are stored in the SNMP Proxy Agent database. To process these requests and update the node and the StarKeeper II NMS Core System and SNMP Proxy Agent databases, you must execute the sksnmpupd command. Execute this command when you want to update the user s operating environment to reflect the stored Set Requests. To examine the results of the sksnmpupd command, look at the file $SNMP_LOG/snmp_set.log. To browse through the log file, you can use such UNIX tools as pg, cat, or vi. If any requests fail, correct any error conditions and execute the sksnmpupd command again. See Appendix A, User Reference for details on sksnmpupd. Refer to Appendix C, Supported SNMP MIB Objects and Traps to see which objects can be set. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 2-5

38 Administration and Maintenance Procedures Cleaning Up Log Files 2 Periodically go to the log file directory, $SNMP_LOG, and check the size of your log files. Check log file snmp_agent.log and delete log entries that you no longer need. You can use the UNIX editor vi to clean up the log files. 2-6 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

39 Database Management 0 3 Overview 3 The SNMP Proxy Agent utilizes the INFORMIX database management system. The SNMP database is created automatically when the SNMP Proxy Agent is installed. Before SNMP Managers can access the SNMP Proxy Agent, you must administer the SNMP database so that it contains information about the SNMP Proxy Agent host system, the SNMP Managers, and the network interfaces that the SNMP Managers can manage. This chapter provides the following: A description of how to register an SNMP Manager into the SNMP database A sample scenario that shows how a group of SNMP Managers could be defined in the SNMP database. Instructions for the menus and screens used to maintain the data in the SNMP database and to generate reports. This chapter describes the two versions of the user interface: the ASCII version and the Motif version. Refer only to the section that describes the version you are using. SNMP Proxy Agent Planning 3 Before entering information into the SNMP database, plan the system. Use the planning forms in Appendix A to help you gather and organize the information you need. You may also find it helpful to read Sample Scenario to see how the information can be organized. Once you have gathered and organized the appropriate information, use the following procedure. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 3-1

40 Database Management Procedure 3-1. Planning for the SNMP Proxy Agent 1. After the SNMP Proxy Agent is installed, enter System Information into the SNMP database. System Information describes the host system for the SNMP Proxy Agent. For example, it includes the name of the host for the SNMP Proxy Agent and contact information the customer uses when there is a problem with the SNMP service. 2. Identify the network interfaces that the SNMP Proxy Agent supports. Network interfaces are ports on a BNS-2000 node, BNS-2000 VCS node, or BNS-2000 MPC (concentrator). You must assign a unique numeric identifier (Interface Index) to each of the network interfaces that the SNMP Proxy Agent supports. An Interface Index can be any number from The SNMP Managers use the Interface Indices in their SNMP queries to identify the Frame Relay or SMDS interfaces that they use. Interface Indices do not have to be assigned sequentially. Rather than assign Interface Indices arbitrarily, develop a numbering plan that suits your needs. 3. Determine the set of network interfaces that an SNMP Manager can manage. Each set of network interfaces that an SNMP Manager can manage is grouped together in a Customer View. A Customer View is identified by a unique name and includes one or more Interface Indices as members. When an SNMP Manager queries the SNMP Proxy Agent, it receives data for those Interface Indices that are included in its Customer View. 4. Identify each SNMP Manager in the SNMP database and assign a set of Customer Views and community strings to each SNMP Manager. Each SNMP Manager must be identified by a unique Id called a Subscriber Identifier, its IP address, and a set of community strings (passwords) and Customer Views. You can assign the same Customer View to more than one SNMP Manager. Each SNMP Manager can have three community strings and three Customer Views: The Read Community String is used by the SNMP Manager when issuing SNMP Get and Get-Next Requests. The Write Community String is used by the SNMP Manager when issuing SNMP Set Requests. 3-2 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

41 Database Management The Trap Community String is used by the SNMP Proxy Agent to send traps to the SNMP Manager. The administrator of the SNMP Manager should supply you with the Trap Community String. The Read Customer View defines the set of network interfaces that an SNMP Manager can manage. The Write Customer View defines the set of network interfaces that an SNMP Manager can modify (set). The Trap Customer View defines the set of network interfaces that an SNMP Manager receives traps for. You can specify the same or different Customer Views for reading, writing, and for traps. 5. Make sure that the SNMP database is synchronized with the node and StarKeeper II NMS Core System database. For more detail, refer to Synchronizing the SNMP Database. Sample Scenario 3 The following scenario illustrates how a group of management stations could be identified in the SNMP database. Company XYZ has three divisions each with its own SNMP Manager: Sales, Marketing, and Headquarters. The company-owned LANs for Sales and Marketing are interconnected. The Sales and Marketing SNMP Managers will manage the network interfaces for both Sales and Marketing. Headquarters monitors all network interfaces for Company XYZ. The SNMP Manager in the Sales division connects to the network interface identified by Interface Index 10, Marketing uses Interface Index 11, and Headquarters uses Interface Index 100. In addition, Marketing will receive traps for only the network interface it uses. Headquarters and the Sales division will receive traps for the same interfaces they monitor. Look at the following sample Customer Profile Worksheet to see how the administrator of the SNMP Proxy Agent set up the SNMP database for Company XYZ so that these goals were met. A blank Customer Profile Worksheet is included in Appendix A, User Reference. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 3-3

43 Database Management MASTERVIEW 3 There is a Customer View called MASTERVIEW that is automatically created when the SNMP database is initialized. MASTERVIEW, as the name suggests, gives you a global view of your customer network. MASTERVIEW is a list of all the Interface Indices that you have defined. Each time you add or delete an Interface Index, MASTERVIEW is automatically updated. If you assign MASTERVIEW to your local SNMP Manager, you will be able to get information about all the network interfaces (Interface Indices) in the SNMP database. If you assign MASTERVIEW to any other SNMP Manager, that SNMP Manager can also get network management information about all the Interface Indices in the SNMP database. NOTE: The name MASTERVIEW is reserved for the system-generated Customer View. No other Customer View can be named MASTERVIEW. Synchronizing the SNMP Database 3 After you add a new network interface to the SNMP database or change an interface configuration, such as adding a new DLCI to a Frame Relay interface or changing the access class on a SMDS DS3 interface, additional customer network management information must be collected from the node and from the StarKeeper II NMS Core System database and stored in the SNMP database. You use two commands to collect this data: sksnmpndsync and sksnmpdbsync. These commands run as cron processes, but can be executed manually to update the SNMP database immediately. These commands are described below and in Appendix A, User Reference. sksnmpndsync 3 The sksnmpndsync command retrieves SMDS Access Class information and Frame Relay DLCI numbers from the nodes for those Interface Indices that you have provisioned in the SNMP database. It retrieves the information and stores it in the SNMP database. This information is automatically updated in the SNMP database by a cron process. As a cron process, this command retrieves information from the nodes for any new Interface Index that you have added to the SNMP database. StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1 3-5

44 Database Management If you want the Access Class or DLCI information updated immediately, you must run this command manually to update the Interface Index in the SNMP database. You must run sksnmpndsync manually if you have done any of the following: Added a new Frame Relay or SMDS DS3 Interface Index Changed the SMDS Access Class for an SMDS port on the node that you have provisioned an Interface Index for. Added or deleted a Frame Relay DLCI number to a Frame Relay port on the node that you have provisioned an Interface Index for. sksnmpdbsync 3 The sksnmpdbsync command retrieves SMDS configuration information from the StarKeeper II NMS Core System database and assigns this information to the Interface Indices and Customer Views in the SNMP database. For example, this command retrieves such configuration information as SMDS individual/group addresses and SMDS individual/group screening addresses. This command runs as a cron process. However, if you want the updates done immediately, you can run sksnmpdbsync manually. For more information on this cron process, refer to Crontab for cnmsadm in Appendix A, User Reference. Flow Control and Usage Counts 3 Some SNMP requests require the SNMP Proxy Agent to query the switch node directly for data, causing additional traffic and possible congestion on the node. The SNMP Proxy Agent enables you to restrict the number of queries made to a node and to get reports on SNMP traffic statistics. Usage Counts 3 The SNMP Proxy Agent maintains usage counts for each SNMP Manager and totals for all SNMP Managers. You can get reports on usage counts by using sksnmpstat, sksnmpcf, or sksnmpxadm. NOTE: Only SNMP Managers that are CNM servers can request current cumulative SNMP usage statistics by using SNMP to query the snmp group of objects. For each SNMP Manager, the SNMP Proxy Agent keeps track of several statistics, such as the number of times the SNMP Manager accesses the SNMP Proxy Agent, the number of SNMP errors an SNMP Manager has made, and the number of SNMP packets received and sent. These usage counts accumulate until you reinitialize them through sksnmpcf or sksnmpxadm. 3-6 StarKeeper II NMS SNMP Proxy Agent Guide R10.0, Issue 1

45 Database Management The SNMP Proxy Agent also maintains totals for usage by all SNMP Managers from the time the SNMP Proxy Agent was last started. These usage counts are reinitialized when the SNMP Proxy Agent is restarted. These usage counts are known as current_totals. Flow Control Parameters 3 The SNMP Proxy Agent enables you to restrict the number of queries made to a node by an individual SNMP Manager or by all SNMP Managers. For more information, see the description of the menu option in this chapter. SNMP Proxy Agent Motif User Interface 3 The SNMP Proxy Agent's Motif user interface utilizes the features of the OSF/ Motif user environment and the Hewlett-Packard Visual User Environment (HP VUE). This section provides instructions for using this user interface. Procedure 3-2. Accessing the SNMP Proxy Agent Motif User Interface 1. Log in as cnmsadm in the Hewlett-Packard Visual User Environment (HP VUE). 2. Make sure that the environment variable DISPLAY is set correctly. 3. At the prompt, enter sksnmpxadm, or sksnmpxadm & to start the process in the background. The StarKeeper II NMS SNMP Proxy Agent main window displays.
